The response of RC(reinforced concrete)shear wall with different shear span ratios and axial compression ratios under quasi-static load and dynamic load with high strain rate is studied using finite element software ABAQUS.Then the results are compared with the results calculated according to codes after considering strain rate effect,to obtain the influence of strain rates on aseismic capacity of RC shear wall.Through comparing the failure mode and bearing capacity of shear wall under various shear span ratios,axial compression ratios and strain rates,it can be concluded that: with the increasing of strain rate,the seismic bearing capacity of shear wall will increase if the shear span ratios and axial compression ratios of shear walls are the same.So the strain rate effect should be taken into account properly in the seismic analysis of RC shear wall.
